SYRINGE.

SPECIFICATION forming part of Letters Patent No. 321,850, dated July 7,1885.

Applicationiiled April 30, 1885.

To LZZ whom, it may concern:

Be it known that I, GEORGE E. PHILBRICK, a citizen of the United States,residing at Manchester, in the county of Hillsborough and State of NewHampshire, have invented certain new and useful Improvements inSyringes; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to theletters and figures of referencemarked thereon, which form apart of this speciication.

This invention relates to improvements in vaginal syringes; and itconsists in the construction and combination of the several partshereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a plan or top view of the backreceiving-reservoir. Eig. 2 shows a view of the cushion. Fig. 3shows thetwo-part inlet-pipe. Fig. 4 shows a side view and a sectional view ofthe flanged washer; and Fig. 5 is the complete syringe, having thereservoir, the inlet-pipe, and the spray-tube in section.

a is the back receiving-reservoir,made preferably of non-corrosive metalor hard rubber, and made funnel-shaped, and provided with anipple,a,surrounding the exitopening,adapt ed to receive the end of thedischarge-tube b. The nipple may be constructed, as shown, so that theiiexible rubber tube can be sprung on it; or it may be provided withascrew-thread to receive a correspondingly-threaded couplerring held inthe end of the pipe b. The reservoir is made funnel-shaped, so as topresent no angular surfaces to catch and retain any mucus or othermaterial carried in the outiowing water. An annular cushion, c, of softrubber or other suitable material, is placed on the upper edge of thereservoir. Itis formed with an inwardly-projecting shoulder, c, whichextends over and rests upon the upper edge ofthe reservoir. It also hasthe depending iiap or wing c2, which is made tapered or funnel-shaped inform, corresponding to the shape of the reservoir. The wing o2 is sprungover the upper end of the reservoir, and,by reason of its shape, holdsthe cushion firmly in place and draws the shoulder c firmly against thesaid upper (No model.)

edge. The inner face of the cushion is tapered the inner side 0f thereservoir. It is preferably tapered so as to makeits upper edge thin, asshown, so as to increase its elasticity and permit it more readily toconform to the locality against which it is pressed. ln order to preventthe cushion from being displaced when too great pressure is exerted uponit,a small annular flange, a2, isformed around and near the upper end ofthe reservoir. The wing of the cushion draws down against this flange,but is prevented thereby from being forced any farther.

Near the lower end, and at one end of the axis of the oval reservoir, auopening, a3, is formed to receive the inl et-pipe. The arrangement ofthe opening aa on the longer axis ofthe oval reservoir is for thepurposes apparent to any one acquainted with the use of syringes of theclass to which this invention belongs. The inlet-pipe d is composed ofthe inner tube, d', and the outer tube, d'2. The inner tube has asuitably-threaded end to receive the spray tube or nozzle e,whereby thelatter may be attached or detached at pleasure. It is made in a gradualcurve, as shown, so that its outer end will project through the openinga3 and its inner end stand at or near the center of the` reservoir. Itsupper end is arranged just below the plane of the upper edge of thereservoir, so that the spray tube or nozzle may be readily attachedthereto. It is made preferably in the arc of acircle, so that it mayreadily be inserted through the opening a3. It has a circumferentialflange, d3, arranged to fit snugly against the inner side of thereservoir and make a water-tight joint. Its end projects to the outerside, and is provided with threads to receive thecorrespondingly-threaded socket on the end of the outer tube, d2. On theprojecting end of the tube d atapered washer, d4, is placed, as shown,which is adapted to fit snugly against the outer side of the reservoirand make a water-tight joint; or,in place of the washer, a boss may bemade on the outside of reservoir. The end of the outer tube, d2, jamsagainst the outer side of the washer or boss, as shown. The washer, whenused, is provided with an annular rim-1iange, d5, in order to give itgreater bearing-surface and thereby If desired, a gasket, d5,

make a better joint.

\ to correspond approximately with the taper of IOO of rubber or othersuitable material, may be placed between the Washer or boss andthereservoir, in order to make a more perfeet joint or to close small leaksconsequent upon imperfeet Construction of the Opening` a and piped. Tothe pipe or tube di the end of the supplypipef, with its bulbf, isatttaehed, as shown.

The manner of using` the syringeis obvious, and need not be explained atlength.

The results secured by thissyringeare, iiret, perfect cleanliness;second, freedom from leal;- age; third, ease with which it may beapplied and heldin place; the projecting end of the pipe affords supportfor one or more of the iingers, while the other iinoers may be claspedaround the lower smaller end of thereservoir; fourth, the eoaptation issneh that it can be used in a standing, sitting, or reclining position;fifth, the several parts maybe easil y separated for packing or otherdesired purpose, and be as easily and quickly put together.

Having thus described my inventioinn'hat I claim, and desire to secureby Letters Patent, 1s-

1. The eonibinatio1i,with the funnel-Shaped back rceeivingreservoir, ofthe inner curved pipe, d, pipe provided with annular flanges di, theouter pipe, di, threaded onto the outer projeeting end ofthe pipe df,and the tapered washer or boss d, substantially as set forth.

2. The cornbinationgvith the fnnnel-sl1aped or tapered backreeeivingaeservoir, of the annular cushion provided with aninwardly-liniejeeted shoulder covering,` the upper edge of the reservoirand having the depending annular tapered flap or wing to be sprung overthe outer side oi'lhe upper end of the said reservoir, and the annularsustainingring ai, projecting from the reservoir, substantially as setforth.

In testimony whereof I ai'iix my signature in 4o presence of twoWitnesses.
